Abstract
In the title compound, C19H12Cl2N2O5S3, the benzene rings of the chlorophenylsulfonyl groups form a dihedral angle of 35.85 (8)° and are inclined at angles of 23.51 (6) and 59.22 (6)° with respect to the essentially planar benzisothiazole ring system [maximum deviation = 0.030 (2) Å]. The molecular conformation is stabilized by an intramolecular C—H⋯O hydrogen bond. In the crystal packing, molecules are linked into chains parallel to the a axis by intermolecular C—H⋯O hydrogen bonds and π–π stacking interactions, with centroid–centroid distances of 3.592 (5) Å.
